To all whom it may concern:

Be it known that I, FREDERICK R. PARKER, a citizen ofthe United States of America, residingat Chicago, in the county of Cook and State of Illinois,v have invented a new and useful Relay,of which the following is a specification, reference being had to the accompanying drawing, illustrating same.

This application is a division of the United States patent application from which Patent No. 1,226,617 issued on May 15, 1917-.

My present invention relates to that class of electrically-operable devices known as relays. c

- The principal objects of my invention are, to provide an improved relay, electricallyoperable device, or electrically-operable mechanism, as herein set forth; to provide improved switching mechanism for such a relay, device, or mechanism, as herein disclosed; and to provide improved means for operatin the switching mechanism, as herein disclose Other objectswill be apparent from the following specification.

The figure of the drawing is a side elevation of one preferred construction of my improved relay device, with a portion removed,

1 showing the relay mounted to a mounting strip which is shown in cross-section. The

.portion which is" removed from the figure is a portion of the front insulating spool head, and it is removed to show the construction of the device more clearly.

Referring to the drawing, 1 is a magnetizable core upon which an energizing coil 2 is wound, 3 and 4 are heads of insulating material which} are forced onto the core 1 and form therewith a spool for containing the winding 2. 5 is an L-shaped member of magnetizable material, attached to the rear end of the core 1, preferably by a bolt 6 extending into the rear end of the core 1. One leg of the member 5 extends substantially parallel with the core 1, from the spool head 4 to the spool head 3, preferably as shown, and is preferably attached to the heads 3 and 4 in any sultable manner. 7 is a mounting strip intended for carrying a number of relay devices mounted thereon. The relay of the drawing is held to the strip 7 preferably by nuts 8 8 which are screwed onto the mounting bolt 6. 23, 24 and 25 are switch springs which are preferably carried by the insulating head portion 4 and member 5. These springs 23, 24 and 25 are insulated from each other at their mounting, in any suitable manner. 11 is one of a pair of terminals for the ends of the winding 2, which terminals are extended through the insulating'head portion 4 and carried thereby. In the drawing, one of the terminals 11 is directly behind the other. The ends of the winding 2 may be attached to the respective terminals 11 11 as shown, preferably being soldered thereto. 13 is an'armature which is preferably made of comparatively thin m'agtttetizable material and is mounted pivotally to the forward end of the L-shaped member 5 preferably by a screw 14. The upperor inner end of the armature 13 preferably carries a pin 15 of insulating material adapted to bear against the switch spring 24 and operate it when the armature 13 is operated. 16 is an adjustment screw for limiting the backward movement of the armature 13. The front end of the core 1 is preferably cut out as shown, to accommodate the armature 13 and provide a portion 17 extending forwardly to within a short distance from a second armature 18. The armature 18 is preferably made of comparatively thick magnetizable material and is pivotally mounted at 20 to a bracket 19 which is attached to the spool head 3 preferably as shown. In the construction shown, the armature "18 overlaps the armature 13, and preferably carries an insulating roller 21 at its free end adapted to bear against the upturned end of the switch spring 24 and operate the spring 24 when the armature 18 is operated. 22 is an adj ustment screw for limiting the backward movement of the armature 18. The switch sprin 24 co-operates with the springs 23 and 2 when operated, to control the switch contacts therewith.

All other details of construction of the device are thought to be well understood without further description.

The operation of the relay illustrated is as follows:

When a small energizing current of the proper intensity is sent through the energizing coil 2, the magnetic circuit 1 5 13 becomes sufficiently magnetized to cause the v the switch spring 24 and causing core 1 toattract the armature 13 thereto, in a manner well understood, thus operating it to disengage. the spring 23, thereby opening the 5 switch 23 24. The armature '18 will not,

. energizing coil however, be attracted by this weak energizin current.

Vhen a larger energizing current of the prgper intensity is sent through the 2, the magnetic circuit 1 5 13 18 becomes sufliciently magnetized to cause the attraction of both of the armatures 13 and 18 toward the core 1, although the" armature 13 may already 15 have been attracted by a previous current of weaker intensity, whereupon the armature18 operates the switch spring 24 from where the armature 13 left off, still farther in the same direction, andthereby causes it to engage the spring 25 and thus close 25 switch 24 25. When the energizing current the switch 24 25.

When the energizing currentis reduced sufiiciently, the armature 18 becomes released, as well understood, thus opening the is reduced substantially to zero, the armature 13 becomes released, thereby closing-the illustrated the attraction of armature 13' switch 23 24.

It will be noted that in the construction armatures, the armatures controlling the respeetive switches. It will also be noted that the plurality of'switches have a common switch member.

When a very small CllI'lQllt is-sent through 40 the energizing winding 2 and is then gradthere is a large energizing current passing ually increased, the armature 13 first becomes attracted and opens the switch 23 24,

and then the armature 18 becomes attracted and closesthe switch 24 25. Reversely, when through the energizing winding 2 and it is gradually decreased, the armature "18 firs becomes released and opens the switch 2 24, and then the armature 13 becomes released and closes the switch 24 23.

I may utilize the above-describedoperations of the armatures, and their contTrol of the proper switches, in various places to advantage, as in telephone systeny for con trolling signals and other apparatus and circuit arrangements.

The backward operations of the armatures 13 and 18 may be caused by the pressure of spring 24 thereon, or by gravity, or

both.

I desire it to be understood that may vary the combination of switch springs or the construction of the switching mechanism or operable mechanism to suit the re-- quirements, without departing from the scope of the'appended claims, and I do not, therefore,-wish to be limited in this invention to the particular construction shown.

I also wish it to be understood that I may employ one or more energizing coils or windings on the core 1, or,in fact, various means, for magnetizing or energizing the device of this invention, or for varying the magnetism or energization thereof, to suit the requirements.

' 13 also wish it to be understood that I may vary the construction and arrangement of the armatures to suit the requirements, without departing from the scope of the appended claims, and I do not, therefore, wish to be limited in this invention to the particular armatures shown.

While the construction of the relay device he'rein shown provides a sensitive and efiicient device, I do not wish to be limited in this invention to the particular details herein set forth, as various modifications thereof may be made or utilized in various Ways without departing from the scope of the appended claims.

The preferred form of relay of this invention, and a modified form thereof, are illustrated and described in my United States Letters Patent No. 1,226,617, dated May 15,

1917, of which this present application is a division, and the electrom'agnet structure of the preferred form of relay of this invention is claimed in my. said Patent No. 1,226,617.
